Annular Cutters
Annular Cutters are precision-engineered hollow drill bits designed to remove only the material at the periphery of a hole, creating cleaner and faster cuts than conventional twist drills. Known for efficiency in producing large-diameter holes, annular cutters are widely used in metal fabrication, structural steel work, and heavy engineering projects in Pakistan.
Modern annular cutters are made from high-speed steel (HSS), cobalt steel, or solid carbide, with advanced coatings like TiN or TiAlN that reduce friction and extend tool life. Their cutting edges are engineered with multiple teeth that shear through material effectively, leaving burr-free finishes. Compared to twist drills, annular cutters consume less power, produce less heat, and generate smaller chips for easier cleanup.
The applications of annular cutters include structural steel fabrication for bridges and buildings, railway construction for drilling tracks and beams, automotive and aerospace industries for chassis and component machining, and maintenance operations in oil & gas facilities. They are frequently used with magnetic drill presses for portability and precision on-site.
Performance is optimized by selecting the correct cutter size, applying proper lubrication, and maintaining sharpness. Pilot pins are used to guide the cutter, eject slugs, and allow coolant flow, enhancing cutting accuracy and prolonging tool life. Regular inspection and re-sharpening further extend usability.
